 according to the dietary protein level. Group A (n=5) received 10% crude protein level feed, group B (n=5) received 15% crude protein level feed, while group C (n=5) received 20% crude protein level feed. The rams were fed for a period of 12 weeks before the testicles were harvested. Gonadal reserves of rams fed 20%, was highest with values of 43.3 ± 3.9 (x10<sup>6</sup>/g) and 47.0 ± 2.5 (x10<sup>6</sup>/g). This was followed by rams fed 15% C. P. and 10% in decreasing order (28.0 ± 3.9 x10<sup>6</sup>/g, 37.7 ± 2.5 x10<sup>6</sup>/g and 20.7 ± 10.1 x10<sup>6</sup>/g and 36.0 ± 14.6 x10<sup>6</sup>/g). These differences were not statistically (P > 0.05) different. Rams fed 15% had the highest <i>caput</i> epididymal reserves with values of 15.3 ± 0.7 (x10<sup>6</sup>/g) for right epididymis and 16.7 ± 11.6 (x10<sup>6</sup>/g) for left epididymis. It was observed from this study that varying levels of protein diets using cotton seed and palm kernel cakes had no significant difference in gonadal and extragonadal sperm reserves of Yankas rams.&picture=http://www.aascit.org/aascit/decorators/img/journal/805.jpg)

The aim of this study was to evaluate the effects of graded levels of dietary protein using cotton seed and palm kernel cakes on gonadal and extragonadal sperm reserves of Yankasa rams. A total of 15 rams aged 19.06 ± 2.4 months and weighing 19.4 ±1.6 kg with good body condition scores of 3.5 were divided into three treatment groups (A, B and C) according to the dietary protein level. Group A (n=5) received 10% crude protein level feed, group B (n=5) received 15% crude protein level feed, while group C (n=5) received 20% crude protein level feed. The rams were fed for a period of 12 weeks before the testicles were harvested. Gonadal reserves of rams fed 20%, was highest with values of 43.3 ± 3.9 (x106/g) and 47.0 ± 2.5 (x106/g). This was followed by rams fed 15% C. P. and 10% in decreasing order (28.0 ± 3.9 x106/g, 37.7 ± 2.5 x106/g and 20.7 ± 10.1 x106/g and 36.0 ± 14.6 x106/g). These differences were not statistically (P > 0.05) different. Rams fed 15% had the highest caput epididymal reserves with values of 15.3 ± 0.7 (x106/g) for right epididymis and 16.7 ± 11.6 (x106/g) for left epididymis. It was observed from this study that varying levels of protein diets using cotton seed and palm kernel cakes had no significant difference in gonadal and extragonadal sperm reserves of Yankas rams.
